2.1 Power Options
Power-over-Ethernet (PoE) becomes a common technology as many sites adding PoE to
support VOIP telephony and wireless access points. Jack PC devices are especially built to be
powered by Power-over-Ethernet infrastructure. However, where there is no PoE switch
available, Jack PCs can be powered through a Midspan injector or with the external power supply
supplied by Chip PC.
1) PoE Switch Available
The Jack PC thin clients are connected at the back side through Ethernet cables to the building
LAN and receive Power-over-Ethernet through the existing CAT-5 enterprise infrastructure. Jack
PC, is the world’s lowest power desktop, consumes only 5W at full work mode, which means
significant costs-savings to the enterprise.
The Jack PC supports the industry PoE standard 802.3AF. Check that your switch has 802.3AF
support, if you are not sure – check with your Switch provider, see section 6.6 for more
information.
2) Switch + Midspan PoE Injector
If Power-over-Ethernet is not available, Midspan power injectors can be added to complement
existing LAN switches and create PoE infrastructure for all/specific ports.
3) Standard LAN Switch + External Power Supply
Another option is to use Jack PC devices with external DC power jack enabling standard wall
mounted power supply connection. Jack PC devices should only be used with Chip PC-
supplied power supplies (Chip PC part number: CPN1491 or CPN1503 or CPN1504).
